  • Patent number: 7115335
    Abstract: A fuel cell system has an improved connector assembly to provide for the quick connection of a fuel cartridge and the fuel cell. Two leak resistant connector members with an easy to engage coupling mechanism that stably grips the two connector members to provide for flow between the members. The first connector member is adapted to engage the second connector member to form a unitary structure, which can establish fluid communication between the connector members. Generally, both the first connector member and the second connector member comprise a fluid flow path that can be each sealed/unsealed by a poppet valve or other suitable valve members. In some embodiments, the connector members can be engaged/disengaged by rotating an element of the coupling mechanism. The connector assemblies can be particularly useful for the connection of a fuel cell with a fuel cartridge.

  • Patent number: 6880718
    Abstract: A wafer container having a door with at least one latching mechanism, wherein the latching mechanism has a spring member that holds the latching mechanism at one or more favored positions that preferably correspond to latch-open and latch-closed conditions. In a preferred embodiment, the spring member has an over-center condition that urges the latching mechanism towards the favored positions, thereby resisting unintended actuation of the latching mechanism. Moreover, in preferred embodiments, the latching mechanism has soft stops at the latch open or latch closed condition that minimizes abrupt snapping into position of the latching mechanism. Preferred embodiments utilize a rotatable member configured as a cammed member with an elongate rigid plastic member having at least one node, forming a plastic spring. The spring is pivotally mounted on the rotatable member and pivotally mounted to the door structure.

  • Patent number: 6811029
    Abstract: A wafer container for supporting semi-conductor wafer disks and for interfacing with processing equipment and methods for constructing the same. Wafer supports are positioned within an enclosure portion, the wafer supports having a plurality of vertically stacked shelves for defining slots. The wafer supports are secured within the enclosure portion rigidly at the bottom margin and resiliently at the top margin. In preferred embodiments resilient plastic spring members extend between the closed top and the wafer supports to substantially constrain lateral or forward-back movement of the wafer supports with respect to the closed top and to permit some vertical movement of the wafer support with respect to the closed top. The spring members may be configured as a leaf spring integral with an extending from the top margin of each wafer support.
